For 0-5i, plot point P(0,-5),
with the real part as the x-coordinate,
and the imaginary part as the y-coordinate.
r=5 is the distance to the origin, O(0,0).
theta=270%5Eo (or theta=3pi%2F2 in radians) is the angle OP forms with the positive x-axis,
measured counterclockwise from the positive x-axis.
